My Brera keeps cutting out since a re-fill
I'm Anthony and I have a problem with my Brera 2.4 JTD, 07 and hoped someone could give me an idea of what could be the problem and possible way to fix it.
Last week I was driving home from work when I decided to fill up, It had a quarter of a tank. I went to the closest garage which was a Shell and put in £50 worth of standard Diesel (Deffo put Diesel in, checked a few times to make sure I had diesel pump in my hand haha).
After filling up I drove for about 5 miles down the road, then got caught at some lights. When I pulled off however there was no power in the car and the acceleration did nothing at first, I rolled forward and it gradually picked up speed and I pulled away. I got about 50 meters until the next set of lights and got caught on these, the car did the same thing but this time it juddered then cut out. I tried restarting but it kept starting then cutting out almost straight away. After 5 or 6 attempts the car started and I struggled onto the side road then it cut out again and wouldn't start.
I phoned the RAC and they came out after about an hour, he asked me the questions of "was it deffo diesel" and "where did I fill up". After he was happy it wasn't petrol i had put in he tried the car, It cut out twice then started and stayed on. He was checking things for ages, but couldn't find or see anything wrong. No lights had come up on my dash and no codes came up on his computer. We risked driving it home as I was about 5 mins away, where he tried a few other things but decided it must be dodgy fuel and said to take it to a garage.
Since then it has mostly worked fine, but it has had two bouts of cutting out straight after starting which lasted about half hour then seemed to work fine again. I went out today to take it to the garage. It worked fine at first until I got to my dads first, was in his house for 20 mins then got back in my car and it started cutting out again. That was this morning and it hasn't started since. I'm no car expert but it just seems like if can't get fuel to the engine so cuts out.
I know that was alot to write and I send my apologies but I am just at a loss of what to do.
Any help would be amazing.
